The QuarkChain Network is a permissionless blockchain architecture that aims to meet global commercial standards. It aims to provide a secure, decentralized, and scalable blockchain solution to deliver 100,000+ on-chain TPS. The main features of the QuarkChain Network are: - Flexibility: QuarkChain is a public chain that can support multiple consensuses, multiple transaction models ( including virtual machines VMs), ledger, and token economics in one network. It can reportedly adapt to blockchain innovations by customizing consensus, transaction model (including VM), ledger, and token economics in each shard so that to satisfy different requirements of different industries/enterprises/DApps. The network supports two consensus algorithms, PoW and PoSW ( a combination of PoS+ PoW). More consensus algorithms (DPoS, PoS and etc) will be added into different shards in the future. It is EVM-compatible - every DApp deployed on Ethereum can be deployed in QuarkChain. The team plans to add more virtual machines (e.g. EOS VM) in different shards so that developers have more choices. - Scalability: QuarkChain aims to deliver 100,000+ on-chain TPS. Currently, 55000+ peak TPS has already been achieved in TPS competition held within the community - Decentralization: QuarkChain has a two-layered structure and encourages individual miners with different levels of capability to mine directly without joining mining pools. People can choose to mine either in the root chain or in the shard. - Great Usability: QuarkChain supports Native token which enables each shard to have its own tokeneconomics. It also supports scalable cross-shard transactions. Only one account is required to access entire resources in all shards, and smart wallets simplify the management.
